Question : A alone can complete a work in 16 days and B alone can complete the same work in 96 days. In how many days both A and B together can complete the same work?
Option 1: $\frac{88}{13}$ days
Option 2: $\frac{96}{7}$ days
Option 3: $\frac{96}{13}$ days
Option 4: $\frac{88}{14}$ days
Correct Answer: $\frac{96}{7}$ days
Solution : One day's work of A = $\frac{1}{16}$ One day's work of B = $\frac{1}{96}$ One day's work of A and B together = $\frac{1}{16}+\frac{1}{96}$ = $\frac{6+1}{96}$ = $\frac{7}{96}$ $\therefore$ Together they can complete the work in $\frac{96}{7}$ days. Hence, the correct answer is $\frac{96}{7}$
